1. Close the chest
Put the contents back, press the lid shut and slide the slider closed. Then turn the compass lock randomly.
2. Small drawer and wheels on the bottom
Push the small drawer marked with an arrow on the front all the way back in. Then insert the anchor key into the wheels on the bottom and turn each wheel a half turn (180°) clockwise from the solution. This puts the wheels back in their starting position.
3. Reinsert the cannon part
Push the part marked with an arrow at the bottom of the front of the chest all the way back in. Then put the slider back in.
4. Reinsert the ship's wheel part
Insert the second part marked with an arrow and turn the ship's wheel back a quarter turn counter-clockwise so the part is locked.
5. Code wheels to the starting position
Turn each of the three code wheels on the right side a half turn (180°) from the solution. This puts them back in their starting position. Move the slider below the combination lock to any position.
6. Remove the keys
Turn the key in the middle lock back and pull it out. Then turn the anchor key in the small lock at the bottom right a quarter turn counter-clockwise so the code wheels are locked again, and pull it out as well.
7. Close the arrow drawer
Put both keys back into the drawer on the front left and push it all the way closed.
8. Ball back into the starting compartment
Finally, put the metal ball back into the drawer with the pearl in the shell and close it.
Now the puzzle box can be solved again by other players.
